The Influence Of Dietary Energy Level On The Response To Betaine (2001), M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
A total of 800 pigs were used to evaluate the influence of dietary energy level on the response to betaine in finishing pig diets. Dietary treatments were arranged in a 2 × 2 factorial with or without betaine and two energy density levels as the main effects. No betaine × energy interactions (P>0.05) were observed for the entire feeding period (51 to 210 lb) or for any of the three dietary phases. Pigs fed the high energy diets with added fat had (P<.05) greater ADG, lower ADFI, and improved F/G compared with pigs fed the low energy diets without added fat. Adding betaine to the diet had no influence on pig performance.; Swine Day, Manhattan, KS, November 15, 2001

Kansas Agricultural Experiment Station Research Reports
Three experiments using 63 pigs were conducted to determine if infrared thermography could segregate pigs based on subsequent pork quality. Pigs were subjectively classified as either "hot" or "normal" based on infrared surface temperature of the loin region prior to slaughter. In the first experiment 18 market weight pigs were transported, imaged by infrared thermography and slaughtered immediately after 1 to 4 h of lairage. Differences in meat quality were detected; hot pigs had lower a* (less red) and chroma (less intense red color) values, and higher hue angle (less red/more yellow) values, all of which indicate paler muscle color. …

Kansas Agricultural Experiment Station Research Reports
There were 1,243 growing pigs used to determine the effects of increasing dietary niacin on growth performance and meat quality of pigs reared in a commercial environment. The dietary treatments consisted of a control diet (no added niacin) or the control diet with 12.5, 25, 50, 100, or 500 g/ton of added niacin. Increasing dietary niacin decreased ADFI and improved F:G for the overall study. Increasing dietary niacin improved carcass shrink, ultimate pH, drip loss percentage, and loin color. Increasing dietary niacin up to 50 ppm improved feed efficiency, but higher concentrations (up to 50 ppm) decreased carcass shrink, and …

The Optimal Threonine:Lysine Ratio To Maximize Growth Performance Of Nursery Pigs (2001), B W. James, J C. Woodworth, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
A total of 210 pigs (initially 18.2 lb and 25 d of age) were used in a 21-d growth assay. The seven treatments consisted of a basal diet (14.1% CP) with increasing levels of threonine (45, 50, 55, 60, 65, and 70% of 1.07% apparent digestible lysine) and a negative control containing 0.97% lysine. Increasing dietary threonine improved feed efficiency; however, there was no improvement in growth performance between pigs fed 0.97 and 1.07% apparent digestible lysine. Therefore, these results suggest the requirement for apparent digestible threonine is approximately 60% of lysine for 18- to 40-lb pigs.; Swine Day, Manhattan, …
Effects Of Ingredient And Whole Diet Irradiation On Nursery Pig Performance (2001), J C. Woodworth, M J. Webster, B W. James, D E. Real, Joel M. Derouchey, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports
Two trials were conducted to determine the effects of irradiation of individual ingredients or the whole diet on growth performance in nursery pigs. The response was similar for both trials with pigs fed diets containing irradiated spray-dried animal plasma or soybean meal having increased (P<0.05) ADG compared with pigs fed the control diet with no irradiated ingredients or the complete diet that was irradiated. Also, ADFI (P<0.05) was higher for pigs consuming the diet with irradiated soybean meal compared with those fed the irradiated whole diet. Pigs fed irradiated spray-dried animal plasma also had superior F/G (P<0.05) compared with those fed diets containing irradiated microingredients or if all ingredients had been irradiated before manufacturing. Therefore, irradiation of certain feed ingredients can improve growth performance in nursery, whereas irradiation of all ingredients in the diet or the whole diet does not enhance performance.; Swine Day, Manhattan, KS, November 15, 2001
Evaluating Cloves As A Potential Substitute For Antimicrobials In Nursery Pig Diets (2001), R G. Main, J Ernest Minton, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Evaluating Cloves As A Potential Substitute For Antimicrobials In Nursery Pig Diets (2001), R G. Main, J Ernest Minton, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
We conducted two trials to evaluate the effects of feeding graded levels of cloves to weanling pigs as a substitute for antimicrobials. In the first trial, improvements in ADG were observed in pigs fed the lowest level of clove addition (0.5%) and for those fed carbadox (50 g/ton). The higher levels of clove inclusion (1.0% and 2.0%) tended to reduce feed intake. A second trial was conducted evaluating performance of pigs fed diets containing 0.125%, 0.25% and 0.5% cloves (a different batch than used in trial 1). The was no ADG improvement from added cloves as was observed in the …
The Relationship Between Body Condition Score And Backfat In Gestating Sows (2001), M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
The Relationship Between Body Condition Score And Backfat In Gestating Sows (2001), M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Backfat and body condition score were measured on 731 sows in a commercial swine facility to assess the accuracy of feeding sows in gestation based on body condition score. Body condition score was poorly correlated (r2 = 0.19) with backfat thickness. For example, sows assessed with a body condition of 3 ranged in backfat from 0.3 to 0.9 in. (7.5 to 23 mm). This illustrates the need to find a more objective method of measuring body condition (such as ultrasound) in order to properly adjust feeding levels and thus reduce variation in backfat of sows.; Swine Day, Manhattan, KS, November …

Evaluation Of Ground Corn Germ As An Energy Source In Nursery Diets (2001), C W. Hastad, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Two hundred eighty nursery pigs (initially 30.9 lb) were used in a 21-d growth assay to determine the energy value of ground corn germ relative to corn oil in nursery diets. Increasing dietary corn oil linearly decreased average daily feed intake and improved feed efficiency. However, pigs fed diets containing ground corn germ meal had similar gain and feed efficiency as those fed the corn-soybean meal diet without added fat. These results suggest that the added energy provided by corn germ is not utilized as well as that from corn oil.; Swine Day, Manhattan, KS, November 15, 2001

A total of 432 pigs were used to evaluate the effects of Paylean and dietary lysine on finishing pig growth performance, carcass characteristics and tissue accretion. The 12 dietary treatments included Paylean (0, 4.5, and 9.0 g/ton) and 4 levels of lysine. For pigs fed no Paylean, lysine levels were 0.60, 0.80, 1.00, and 1.20%. For pigs fed 4.5 or 9.0 g/ton of Paylean, lysine levels were 0.80, 1.00, 1.20, and 1.40%. The results indicate that pigs fed Paylean need at least 1.0% dietary lysine to optimize growth, carcass parameters, and tissue accretion.; Swine Day, Manhattan, KS, November 15, 2001

Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted to determine the interactive effects of carnitine status (with or without carnitine in diets fed to sows in gestation and lactation), and added fat and dietary carnitine in nursery diets on growth performance of weanling pigs. Feeding sows diets containing carnitine in gestation and lactation had no effect on growth performance of their pigs through 27-d after weaning. A carnitine by fat interaction (P<0.05) was observed for ADFI from d 0 to 7 and ADG from d 0 to 27 in Exp. 1 with pigs fed carnitine and no added fat appearing to have the best performance. In exp. 2, added carnitine had little effect on growth performance, whereas added fat improved feed efficiency. In conclusion, no benefit to growth performance was observed from adding both carnitine and fat to the diet of weanling pigs in these experiments.; Swine Day, Manhattan, KS, November 15, 2001

Comparison Of Bioaerosol Sampling Methods For Swine Barns (2001), B Z. Predicala, J E. Urban, S B. Jerez, Ronaldo G. Maghirang, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
Two bioaerosol sampling methods (Andersen sampler and filtration sampler) were compared. The two samplers were used to assess the bioaerosol loads in two swine finishing barns. They were similar in terms of the species of microorganisms sampled. The persistent strains of microorganisms were various species of the following genera: Staphylococcus, Pseudomonas, Bacillus, Listeria, Enterococcus, Nocardia, Lactobacillus, and Penicillium. However, the use of Andersen sampler resulted in significantly higher bioaerosol concentrations than the filtration sampler. Thus, it appears that filtration sampling can be used for a qualitative survey of bioaerosols in swine barns while the Andersen sampler is suitable for both …

Influence Of Different Equipment Protocols On Particle Size Determination Of Ground Corn (2001), J C. Woodworth, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted to determine the influence of the tapping bar and sieve agitators (balls and brushes) on determining mean particle size and standard deviation of ground corn. Tapping bar had no influence (P>0.10) on mean and standard deviation; however the presence of balls and brushes on sieves decreased (P<0.002) mean particle size and increased (P<0.0001) standard deviation. These results suggest that balls and brushes should be used when determining mean particle size to assist particle flowability. More research should be conducted to determine the effects of the tapping bar and sieve agitators over a wider range of particle sizes.; Swine Day, Manhattan, KS, November 15, 2001

From d 0 to 14, the mean ADG and ADFI of pigs fed additional lactose, regardless of source, was greater and tended to be greater compared to those fed no supplemental lactose. Pigs fed edible grade whey had increased ADFI and tended to have increased ADG as lactose increased from 9 to 18%. When Dairylac 80 or granular whey was included in the diet, …
